T 0 aZZ whom it may concern:

Be it known that I, Ci-mnnns H. Germ, a citizen of the United States residing at Emeryville', county of Alameda, State of California, have invented certain new and useful Improvements in Toilet Flushes; and I do declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

' This invention relates to improvements in toilet flushing systems, the principal object of the invention being to produce a device for the purpose which will utilize the direct pressure in the ordinary water pipes without the use or necessity of employing ball float or other forms of controlling valves in the flushing .tank or reservoir to regulate the flow of water thereinto, and in which the flushing action of the water is aided by a cushion of compressed air.

Another object is toprovide a double or divided tank with inflow and discharge means so coordinated in operation that while the contents of one portion of the tank are being discharged into the bowl of the toilet, the other compartment is receiving a fresh supply of water.

Another object is'to so arrange and combine the above indicated means that a single movement of a hand lever in either direction will at once cause a flushing and filling operation to take place, this single lever move ment being all that is necessary for the user of the toilet to do. 7

Another benefit'of my device is the fact that there are no rubber or similar composi, tion valvesto become worn or deranged, and no parts which can stick or refuse to func tion and cause the flushing tank to overflow, and cause a constanttrickle of water into the toilet bowl, such as frequently occurs with the present construction of toilet flushes.

The fact that there canbe no great leakage of water into the bowl under any conditionswill be especially appreciatedbythose whose amount of water used and to be paid for is regulated by a meter.

A furtherobject' of the invention is to produce a simple andinexpensive device and yet one which will be exceedingly effectivefor thepurposes for which it is designed.

These objects I accomp i h y means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of ref-- erence indicate corresponding parts in the. several views. 7

Fig. 1 is a side elevation of a toilet showing my improved flush connected thereto.

Fig.2 is a longitudinal section through the intake and discharge valve,

Fig. 3 is a top plan View of the same, detached from the tank.

Fig. 4: is a cross section through the discharge DOItS of the valve taken'on a line 44 of ig. 2. I

Fig. 5 is a similar view through the inlet ports taken on a line '5-5 of Fig. 2.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes an air tight tank, preferably of cast iron and of suitable dimensions, and provided with a transverse wall 2 dividing the tank into two equal and non-communicating chambers 3 and 4:. i

. Rectangular ports 5 and 6 are provided in the bottom of the chambers 3 and 4 respectively, these ports being parallel and positioned close to the division wall 2, and be n relatively long compared to their width.

These ports register with. similar ports 7 and 8 provided in the upper portion ,of a valve body 9, the latter having a flanged face 10 whereby it may be secured to the bottom of the tank.

Turnable iii the body'member9, below the ports .7 andB and extending lengthwise of and centrally between the same is-a tapered valve member 11, which is hollow, such hollow portionbeing divided by a wall1 2 into two separate compartments 18 and 14. The compartment 13 is somewhat smaller than the compartment 1%, and is provided with't-hree ports 15, 16 and 17, ports lio and 17 being substantially diametrically op posed, and port 16 intermediate thereto. Eitherone of the ports 15 or 16 at a time is adapted to register with an intake port 18 provided in the side of the bodyinember .9, this port beingadapted for connection to a Water pipe 19 leading from any "suitable source of pressure supply.

- The ports 15, 16, and 17 are positioned relative to each other and to the ports 7 and 8 in the body so that when the port 15-is in will then align with the port 7 leading to one of the tank chambers the port 17 being then blanked, while when the valve 11 is turned in a manner hereinafter described, the port 16 will register with the intake port 18, while the port 17 will register with the port 8 leading to the other tank chamber, the port 15 then being blanked.

The compartment 14: is provided with two diametrically opposed ports 20 and 21, the port 20 being adapted to register with either at a time of the ports 7 and 8, while the port .21 registers at all times with a large outlet 22 in the bottom of the'body 9, this outlet being adapted for connection to the water flush pipe 23 of the toilet 2a. 7

The ports 20 and 21 are positioned relative to the ports 15 and 16 and 17 so that when communication is open from the pipe 19 to the port 7 and chamber 8, the port 20 is then in communication with the port 8 leading to the chamber 4:, and vice-versa.

A cupped cap 25 is screwed into the end of the body 9 adjacent the large end of the valve 11 therein and spaced somewhat there from. A helical spring 26 bears against the inner face of the cap at one end, the other end seating in a cup 27 having a pointed lug 27 on the outside and central thereof adapted to seat in a V-shaped hole 28 provided in the end wall of the valve member 11. By this means, While the full pressure of the spring is exerted against the valve to seat the same -and prevent longitudinal movement, when the valve is turned, the full area of the end of the spring is not binding against the end wall of the valve to increase the fric tional resistance of turning.

The other end of the valve 11 is provided with a stem 29 projecting beyond the body 9, on which stem is secured a hand lever 30 suitably curved to bring the handle 31 thereof within easy reach of the operator.

In order to limit the range of movement of this lever, the hub 30 thereof has a lug 32 projecting somewhat over the small end 9 of the body member 9, and adapted to abut against lugs 33 thereon, these lugs being spaced apart the necessary distance to give freedom of movement ofthe valve 11 between the two different settings of the ports therein. a

The operation of the devicezwill now be evident from the foregoing description, all the figures on the drawings showing the valve 11 in the same position, that is with the lever 30 in its upmost position. In this position, referring to Fig. 5, wateris being admitted to the chamber 3 through portsZ, 16, and 15 from the water pipe 19.

At the same time, referring to Fig. i, the compartment 4: is being emptied of its contents to flush the toilet through ports 8, 20, and 21. As soon therefore, as the lever 30 is moved to this upmost position, the chamber 3 will start that compartment, with a greater force than it would otherwise have.

From the foregoing description it will be 7 readily seen that I have produced such a device as substantially fulfills the object of theinvention as set forth herein.

While this specification sets forth in de tail the present and referred construction of'the device, still in practice such deviations from such detail maybe resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. A valveocomprising a casing having a pair of transversely spaced ports therein, af

discharge port opposite to'saidiirst named ports, an intake port positioned between said other ports, acylindrical member rotatably mounted in the casing and adapted to be turned by hand, a transverse divlsion wall inthe cylindrical member, the latter being hollow; and ports in each of the charm bers thus formed; oneof the ports in one chamber'being adapted to re ister with the intake port in the casing whi e another port registers with one of said first named casing ports, said last-named chamber-port being adapted to register with the intake port while another port in said chamber registers with theother one of said first named casing-ports, and one of the ports in the other chamber being adapted to constantly register with the discharge portiri the easing while the other port, 18 in alinement with either one of the first named ports in opposed order to the registering there with of the portin the other chamber.

2. A valve comprising a casing having a; pair of transversely spaced orts therein, a. discharge port opposite to said first named ports, an intake port positioned between said other ports, a hollow cylindrical mem+ ber turnably mounted in the casing, and a transverse division wall in the hollow member dividing the same into two compartments, one of said compartments being arranged for constant communication with the intake'port in the casingandalternately -with thevfirst named ofrthe casing ports,

and the other compartment beinv arranged for constant communication wit the discharge port in the casing and alternately with the first named casing ports in reverse order to the other compartment.

3. A valve comprising a casing having a pair of transversely spaced ports therein, a discharge port opposite to said first named ports, an intake port positioned between said other ports, a cylindrical member rotatably mounted in the casing, and longitudinally spaced passage means through said member, certain of said passage means being arranged to allow constant communication from the intake port in the casing to the first named of the casing ports alternately,

and the other passage means being arranged to allow constant communication between the discharge port in the casing and with the first named casing ports alternately and in reverse order to the'alinement therewith of the first passage means.

In testimony whereof I afiix my signature in presence of two witnesses.
